Definitions

  • the present invention relates to a rail of a furniture drawer slide with a molded at the upper end of a guide rail guide portion with raceways for rolling elements held in a cage and at least one mounting bracket which is fixedly connected to the rail and provided with a Anschraubflansch, which at a distance and in parallel runs to the guide bar.
  • Rails of the generic type must on the one hand be able to absorb relatively high load-bearing forces, depending on the loading state or filling state of a furniture extracting part, for example a drawer.
  • the raceways of the guide area must have a high surface hardness in order to be able to permanently resist the loads applied to the raceways by the rolling elements.
  • Rails of the generic type are hitherto mainly made of metal, preferably made of steel, which although it can be ensured that corresponding rails are both highly resilient as well as very resistant to wear in the raceways, the costs are due to the use of sufficiently strong Steel sheets for the production of corresponding rails but relatively high.
  • the state of the art includes, for example, the DE 298 03 210 U1 , the DE 10 2005 002315 , the US 2006/066190 , the EP 1 571 357 A1 ,
  • the present invention has for its object to provide a rail of the generic type which is mechanically highly resilient and extremely susceptible to wear despite significant reduction in manufacturing costs.
  • the rail is made of a composite material of metal and another material such as plastic, ceramic, wood and / or wood fiber materials or the like.
  • the relatively low cost of plastic is used to significantly reduce the total cost of a corresponding rail, without the mechanical strength of the rail This is appreciably affected.
  • wood are to name as an advantage in particular the low cost of procurement of the fibrous material.
  • wood-based materials are materials based on renewable raw materials. Thus, the environmental performance of the products can be increased when using this composite material.
  • a corresponding rail can be sufficiently stabilized and stiffened despite the reduction of the metal content and thus also absorb high static loads.
  • a rail is preferred in which at least the regions of the raceways are made of metal.
  • the guide web is formed with its molded guide portion as a hollow body made of metal and filled with a second material at least partially. Foaming, pouring or ejection with the second material are possible as filling methods.
  • the hollow body can be filled with plastic as well as with a ceramic material, other materials such as fiber materials or the like are conceivable.
  • the resulting cavity can also be partially used for receiving functional elements such as stops, dampers or ejectors.
  • FIGS. 1 to 3 are generally designated by the reference numeral 1 furniture pullout guides shown, which consist essentially of a furniture side fixable rail 2 and a with a furniture extractable part, preferably a drawer, couplable running rail 3.
  • the rail serves as a guide rail of a pullout guide.
  • the rail 2 is fastened in each case via a mounting bracket 4 on a side wall of a furniture body, wherein the in FIG. 2 shown embodiment illustrates that, for example, at the mounting bracket 4, a self-closing device 5 may be attached.
  • a self-closing device 5 can of course be arranged on a mounting bracket 4 and an ejector, a damper or a combination of said components.
  • the rail 2 which has a guide web 2a and an integrally formed on the upper end guide portion 2b, made of a composite material made of metal and plastic.
  • the guide web 2a with the integrally formed at its upper end guide portion 2b as a hollow body made of metal, preferably made of steel, and foamed in its interior with plastic 2c.
  • the guide web 2a with the integrally formed guide region 2b is preferably made of a sheet steel with a maximum thickness of 0.7 mm.
  • a connecting flange 4a of the mounting bracket 4 projects into the cavity 2c filled with plastic and can be welded or otherwise connected, for example, punctually or continuously to the guide web 2a.
  • This connecting flange 4a passes through the hollow body up to its upper limit and engages here in a groove 2d.
  • the connecting flange 4a is angled twice in its lying outside the rail 2 area, whereby a Anschraubflansch 4b is formed, which lies in a lateral distance to the rail 2 and parallel to the guide web 2a of the rail 2 extends.
  • This Anschraubflansch 4b like the FIG. 1 makes clear, be equipped with a receptacle 6 for fixing the already mentioned Diseinzugsvorraum 5 or another comparable functional part.
  • the fixing of the mounting bracket 4 relative to the rail 2 can, as already mentioned, be carried out by welding, but it may be sufficient in individual cases, to fix the mounting bracket 4 by foaming the mounting web 4a in the interior of the cavity.
  • FIGS. 4 to 7 differs from the embodiment described above essentially by the fact that the guide web 2a of the rail 2 is provided with a plurality of locking recesses 2e, in which corresponding locking lugs 4c of the mounting bracket 4 can engage to connect the mounting bracket 4 with the rail 2. By an additional foaming of the cavity an additional support of the mounting bracket 4 relative to the rail 2. Also in the embodiment of Figures 4 to 7, the mounting web 4a of each mounting bracket 4 is guided into an upper groove of the rail 2 and thus additionally secured against tilting.
  • the front mounting bracket 4 is made in one piece with the Diseinzugsdämpferkulisse and the damper mount.
  • FIGS. 9 to 11 illustrates that a Deinzugsvorraum 5 or a comparable functional part can also be attached to the transverse webs 4d one or two mounting bracket 4, wherein the transverse webs 4d of the mounting bracket 4 integrally connect the respective mounting web 4a dipping into the rail profile and the mounting flange 4b.
  • the mounting bracket 4 carries by inserting into the groove of the rail 2, the rail in the region of maximum load.
  • the hollow profile of the rail 2 was open to the bottom.
  • FIGS. 12 to 14 a variant is shown in which the guide web 2a of the rail 2 is closed to the bottom. Accordingly, it is necessary, in the area in which a mounting bracket 4 is to dive with its fastening web 4a in the cavity of the rail profile, provide a slot 2f, such as FIG. 14 very clearly shows.
  • FIG. 13 illustrates very clearly that the molded at the upper end of the guide bar 2a guide portion 2b has an approximately star-shaped cross-section, which in a conventional manner a total of four tracks 2g are formed, which are concave in a likewise known manner and equipped with a radius, the corresponds to the radius of spherical rolling elements.
  • FIG. 12 lets in connection with FIG. 13 clearly recognize that in the region of two tracks 2g outwardly projecting end stops 2h are pronounced, which serve as end stops for the displacement of a spherical rolling elements receiving ball cage. As a result, the displacement of the ball cage is limited and an unintentional separation of rail 2 and ball cage avoided.
  • FIGS. 15 and 16 show an embodiment of the invention, which substantially the embodiment according to the FIGS. 12 to 14 corresponds with the difference that the underside of the guide web 2a of the rail 2 is closed by the bending of the lower, free ends 2i of the guide web 2a.
  • a fastening web 4a of a mounting bracket 4 are introduced into the cavity of the rail profile is intended to provide a slot 2f, as in FIG. 14 indicated.
  • the free ends 2 can be connected to increase the torsional stiffness together material, form, or non-positively.
  • the rail 2 consists of a plastic rail 2c surrounded on all sides by metal, the support of the plastic rail 2c being formed from a thin steel sheet having a thickness of 0.2 to 0.7 mm.
  • FIGS. 19 and 20 is a made of metal, preferably in turn made of a thin sheet steel rail 2 foamed with a plastic 2c.
  • FIGS. 20a and 20b show only by way of example that a running rail 3 a furniture drawer guide 1 can be stabilized, and indeed as shown by the running rail 3 embracing stabilizing bracket 7.
  • Die FIG. 20a shows the combination of the stabilizing bar 7 with the fishing hook 8, thus the position of the fishing hook can be freely selected on the track.
  • FIGS. 21 and 22 make it clear that the rail 2 in its upper, the running rail 3 facing end portion may be equipped with an incision 2k, in the direction of the rail 2 extending expression 3a of the running rail 3 can engage when the running rail 3, for example, in its closed position has been postponed. This results in a non-positive tumbler of a cottonbergsers.
  • the fastening web 4a is provided with lateral shapes 4d, through which the two lower legs of the guide web 2a are resiliently spread during insertion of the guide web 2a into the cavity of the rail profile, so that the mounting bracket 4 already receives a position assurance relative to the rail profile in this pre-assembly position.
  • foaming then takes a final fixation of the mounting bracket 4 relative to the rail 2, but it can also be done here by an attachment by punctiform or continuous welding.
  • the right side of the rail was pre-bent spring-like.
  • the rail 2 consists of a self-stiffened and highly resilient plastic plastic rail 2c, which consists only in the region of their treads 2g with a coating of a thin-walled metal sheet.
  • the essential structure and the operation of the rail 2 corresponds to the embodiments described above, in particular also with respect to the Fest eins opportunities on a side wall of a furniture body. It should be noted that, for reasons of clarity in the embodiment of the FIGS.
  • FIGS. 28 to 30 show the combination of two inventive rails 2 to a central section 10 for a full extension.
  • the middle section 10 is optimized in length in the embodiment according to FIG. 30 for low loads, as they occur, for example, in a pull-out tray.
  • the rails 2 extend in the running rail 3 and the carcass rail 11 beyond the connection angle 6 also to take over support function under load. Furthermore, the leadership behavior is thus improved.
  • the WälzMechshifige (not shown), the outer force introduction points of the connection angle 6 run over.
  • FIGS. 31 and 32 The inclusion of a stop damper 9 in the cavity of the rail 2 is in the FIGS. 31 and 32 shown.
  • FIGS. 33 and 34 An embodiment with bilateral forms 4 d on the mounting bracket 4 is in the FIGS. 33 and 34 shown.
